AUTOMOBILE TOOL.

Continuation of application Serial No. 482,131, filed July 2, 1921. This application filed May 10, 1924:.

' Serial No. 712,267.

This invention is a continuation of my copending application for Letters Patent of the United States for an automobile tool and lock, which was filed July 2, 1921, Serial Number 482,131..

My invention relates to tools and the like to be used in connection with an automobile or motor vehicle. More especially my invention has relation to a device to be employed in connection with the spring bands forming a portion of the transmission of a Ford motor vehicle, whereby such elements are maintained in constricted positions so that the actuating spindles may be readily assembled.

As is well known, the transmission of a Ford motor vehicle includes three drums surrounded by a corresponding number of spring bands that are tightened upon. their respective drums by means of spindles that are reciprocated longitudinally of their axes upon the depression of their respectivefoot pedals. In disassembling or takin down the transmission, the foot pedals and spindles, which are mounted and carried in a casing or cover for the transmission, are removed,

which releases the spring bands so that theythen open to their farthest extent. In assembling this structure great difficulty has always heretofore been experienced in holding the three bands in compressed or constricted positions while the spindles are be ing assembled therewith.

I have devise-d a handy tool that is so designed that it will retain the bands in a compressed or constricted manner around their respective drums while the shell is be ing, replaced over the transmission and the spindles assembled with their proper bands. Further objects of my invention are to provide a structure that is capable of being readily assembled with, and disassembled from, the respective bands, and which is light in construction and occupies but a relatively small space for storage. This handholding tool is of a U-shape and its construction such that the lugs on the ends of the bands may readily he slipped or snapped in succession between the arms of the tool. It is also made in two parts, which facilitates its separation after the spindles have been assemble-d with the band lugs so that the tool may be easily withdrawn from the housing through the restricted band-hole as soon as the cover of the housing has been positioned. I prefer to accomplish the divers Objects in substantially the manner hereinafter described, and as more particularly pointed out in the drawings forming a part of thisspecification and which, in a sense, are diagrammatic for thefpurpose' of illustrating the principles involved.

In the drawings 2- Figure 1 is a top plan of the transmission structure showing the use of my tool in conjunction with the transmission bands, the casing and cover being omitted for clearness.

Figure 2 is an end view of'the hands on the transmission released.

Figure 3 is a face view, slightly in perspective and drawn to a larger scale, of the tool, showing the two members thereof'separated or detached.

Figure 4E is'a lower edge viewof the tool assembled. l Figure 5 is a similar view of one ofthe elements of the band holding tool, showing a modified construction.

The tool forretaining the bands of the Ford transmission in a constricted position comprises a substantially U-shaped structure that is adapted to maintain the bands in such position by engaging the outer edges of the lugs 20 on the bands 21. These bands surround the respective drums 22 of the transmission, and lugs 20 are adapted for engagement with the respective spindles that are journaled in the transmission cover so that by operating the respective pedals the proper band may be compressed or loosened upon its respective drum 22. In assembling this tool with these transmission bands, the bands are constricted manually by the operator and the arms of thetool placed in engagement with the lugs thereon in the position. shown in Figure 1. The tool, being of relative thin gage metal, permits the transmission cover to be placed over the transmission and spindles assembled with their respective bands and the lugs carried thereby.

The hand tool preferably comprises a pair of coacting L-sliaped pieces, as shown in Figure 3 of the drawings, the longer arms 23 ofwhich are slightly tapered in widthtowards their outer ends and are deflected slightly, as shown in Figure 4.. The outer end of one of the arms is beveled or cut oblique, as at w so that in assembling the tool with the bands the inner logitudinal edges of the other arm is positioned against the shorter arm 25 of one of these elements is provided with an aperture 26, and is connected to its companion member by means of a chain 27 having a pin 28 interlocked with two of the links at about the central portion of the chain. Arm 29 of the other member of this structure is substantially the same shape as arm 25, just described, except that it is provided with a bent back or folded por tion 30 along one of its edges so as to provide a channel or pocket between the walls in which arm 25 of the other member may be inserted. An aperture 31 is provided in arm 29 and its bent back portion 30, and after arm 25 has been positioned thereon pin 28 is passed through apertures 26 and 31 to retain the parts in assembly. The bent back portion may be conveniently made by turm ing it back from the lower edge of arm 29, as indicated at 32 in Figure 5 of the drawings, in which event aperture 31 is formed itEowards the edge of arm 29 farthest from its old.

After the U-shaped tool has been mounted upon the lugs of the transmission bands, in the manner shown in Figure 1 the trans mission cover carrying the spindles and pedals is then positioned over the transmission drum, and the lugs 20 will receive their respective spindles and the nuts on said spindles may be tightened. The pin 28 is now withdrawn from the U-shaped tool which separates the parts thereof, and the member forming arms 23 and 29 is withdrawn through the hand opening in the transmission cover, while the other element forming arms 23 and 25 is then drawn through said opening by the chain without liability of the same falling into the transmission case.

transmission of Ford motor cars,- compris ing a pair of substantially L-shaped members formed from sheet metal, one of the arms of one of the members having a portion of the metal folded back upon itself to provide a longitudinal channel between adjacent surfaces of the metal to receive the corresponding arm of the companion member, and removable means for securing said co-ac-ting arms in operative relation to each other, whereby upon the removal of said means said members may be separated by a relative movement between the same.

2. A tool. for use in connection with the transmission of Ford motor cars comprising a pair of substantially L-shaped, members formed from sheet metal, one of the arms of one of said members having a portion of the metal folded back upon itself to provide a longitudinal channel between adjacent surfaces of the metal. that is open upon three of its edges to permit the ready insertion and removal of the corresponding arm of the companion member, and the removable pin inserted transversely of said channel and through the corresponding arm of the companion member whereby said members are detachably secured together in the form of a substantially U-shaped structure, and whereby upon the removal of said pin, said members may be separated by a relative movement between the same.

3. A tool for use in connection withv the transmission of Ford motor cars, comprising a pair of substantially L-shaped members formed from sheet metal, one of the arms of one of the members having a portion of the metal folded back upon itself to provide a longitudinal channel between adjacent surfaces of the metal to receive the corresponding arm of the companion member, removable means for securing said co-acting arms in operative relation to each other, whereby upon the removal of said means said members may be separated by a relative movement between the same, and one of the parallel arms of said structure being formed obliquely at its outer end so that the inner edge of said arm extends beyond its outer edge to permit the lugs on the transmission band, when the tool is in use, to be successively moved towards each other and ride over the oblique portion of the arm and latch against the inner edge of said arm.
